IncludeTemplate or ExcludeTemplate

Hi,

If I'm trying to control what gets indexed, should I use IncludeTemplate or ExcludeTemplate in the CoveoSearchProvider.config? If I add a couple of value in IncludeTemplate and re-index, then it indexes just a few items as expected. It doesn't index anything in core.
{0E1410ED-0AEF-4715-9950-6B131B642DE2}
{AFCE0E4A-9225-47B8-BE51-F3940E1E3F45}

Yes, the error goes away, if i comment out the includetemplate. Now I'm actually using the InboundFilters configuration to add the path, I need indexed. Is there a way to specify path that I don't need indexed? Or is that something I would have to custom write?
